In the search of English papers, some schools or institutions may set different requirements for different parts, such as abstract and text, but for abstract papers, the overall search rate is usually less than 30%.
Therefore, when writing English review papers, we need to pay special attention to the writing of cited documents and literature reviews, try our best to use the original language and expressions, and avoid directly quoting other people's original texts or sentences, so as not to lead to high repetition rate. At the same time, when writing English summary papers, it is also necessary to determine the allowable range of duplicate checking rate according to the specific requirements of schools or institutions.
If there is any uncertainty, you can consult the teachers of the school or the heads of academic institutions.
